Yes, a pneumatic motor can work underwater if it is designed with proper sealing, rust-resistant materials, and a reliable air supply system that accounts for water pressure.
modec Air motors are suitable to perform in underground applications, as they are designed with advanced waterproofing, using high-performance INOX stainless steel for parts in contact with water, effective seals to prevent air bubble escape, and a system that collects exhaust air to be vented outside the water, allowing for extended maintenance-free operation.
To find an equivalent pneumatic motor, follow these steps:
Determine the required power, either by using the power of your current motor (if known) or by determining the required torque and nominal speed, then calculating the power:
Power (W) = Torque (Nm) × Speed (rpm) / 9.55
Start by looking for a power range equivalent to or closest to your requirement.
Ensure you have the required air flow and pressure for this power range.
Choose, among the motors offered in this range, the one that matches the torque and speed characteristics of your current motor.
Pay attention to other features that may be important for your application, such as: stall torque (maximum torque delivered by the motor), starting torque (torque available to start the motor under load), no-load speed, weight and dimensions, motor flange and shaft, straight or right-angle head, integrated control handle, and any specific options.
Do not hesitate to consult and compare manufacturers’ datasheets, and/or contact specialized technicians or the manufacturer directly for recommendations tailored to your needs.
By following these steps, you will be able to identify a pneumatic motor equivalent that meets your application requirements.
Wear the required PPE, including hearing protection. Note, however, that you can choose the silencer option to reduce noise levels.
Check that the air supply hoses are in good condition and suitable for the required pressure, flow rate, and lubrication.
Use whip-check devices.
Work in a clean, well-lit environment.
Have the necessary knowledge and skills to handle pneumatic tools safely.
To ensure user safety and equipment protection, it is strongly recommended to use a safety device that integrates several essential functions: emergency stop, automatic downstream circuit purge, pressure drop detection, and automatic air supply shut-off. Our SAT Box perfectly meets these requirements.
Perform maintenance at least once a year based on your usage, and only use original parts and maintenance kits approved by Modec.
Safety First : Ensure the motor is disconnected from the air supply and that you are wearing appropriate personal protective equipment (PPE).
-Disassemble the Motor : Carefully take apart the motor, noting the arrangement of parts for reassembly. Use appropriate tools to avoid damaging components.
-Inspect Components : Check for wear and damage on parts such as bearings, and seals. Look for signs of corrosion or contamination.
-Clean Parts :Use a suitable cleaning solution to remove dirt and debris from the motor components. Ensure all parts are dry before reassembly.
-Replace Worn Parts : If any components are damaged or excessively worn, replace them with new parts. Ensure that replacements are compatible with your motor model.
-Reassemble the Motor: Carefully put the motor back together, following the notes you made during disassembly. Ensure all seals are properly seated to prevent air leaks.
-Lubricate: If applicable, apply the recommended lubricant to moving parts as specified in the user manual.
-Test the Motor: Reconnect the motor to the air supply and test it to ensure it operates correctly. Check for any air leaks and listen for unusual noises.
-Regular Maintenance: Implement a regular maintenance schedule to prevent future issues, including cleaning and lubrication.

Choose a motor suitable for the application in terms of torque and speed.
Respect the motor’s maximum supply pressure (typically 6.2 bar / 90 psi).
Use a high-quality, well-maintained FRL unit (Filter, Regulator, Lubricator) with 40 μm air filtration.
Air lubrication (and thus the FRL unit) should be located close to the motor (ideally within 3 m or less).
Use an appropriate oil in the correct quantity and quality.
Respect the operating temperature range.
Do not run the motor at no load and maximum speed for more than a few seconds.
Perform regular motor maintenance (replacement of vanes, bearings, and exhaust filters).
Store the motor in a dry location to prevent corrosion. Add 10 drops of oil into the air inlet and run the motor for a few seconds before storage.
Before restarting after storage, add 10 drops of oil into the air inlet.
MODEC recommends performing maintenance once a year or every 700 operating hours to ensure that the motor maintains its original performance.
Maintenance should be carried out by trained and qualified personnel.
Use original parts provided in Modec maintenance kits.
Refer to the video tutorials available online.
Motor maintenance should be performed in a clean and suitable environment.
By following these recommendations, you ensure optimal performance and an extended service life for your modec pneumatic motor.
An air motor, or pneumatic motor, is a motor that gets its mechanical power from gas expansion, usually compressed air. When pressurized air is injected, it pushes moving parts inside the motor, creating a rotational movement. This movement can then be used to drive a tool or a machine.
To learn everything about pneumatic motors, consult our complete guide.
Pneumatic motors come in different types depending on torque, speed, precision, and working environment:
Vane motors: compact, robust, and versatile. Ideal for portable tools, robots, and industrial equipment.
Radial piston motors: provide high torque at low speed. Used for machining machines, winches, and heavy-duty applications.
Axial piston motors: compact and suitable for high speeds. Perfect for mobile equipment and air-converted systems.
Turbine motors: very high speed, low torque. Suitable for grinders and high-speed drills.
Oscillating motors: precise motion over small angles. Ideal for positioning and automation.
Gear motors: robust with constant starting torque. Used in demanding industrial environments.
Each type meets specific needs, from high torque to extreme speed or precise motion.
To choose your pneumatic motor, start with your application: what power, torque, and speed are required? If you know two of these parameters, you can calculate the third using the formula:
Power (W) = Torque (Nm) × Speed (rpm) / 9.55.
Then, select from the range the torque/speed combination that fits your needs. Also, ensure that your compressed air supply can provide the required flow for the motor.
For more advice and application examples, check our blog or contact our experts.
To make the right choice, you should refer to the motor’s application.
If the motor is used manually, a handle is often necessary for safe control of start and stop:
Safety handle: with a trigger to easily control start/stop.
Progressive control handle: allows ergonomic and continuous speed control.
These handles prevent unintended starts.
Right/left reverser: manually changes the rotation direction.
If the motor is to be integrated into a machine, the choice depends on size and weight:
Straight motor: compact, lightweight, and easily controllable remotely.
Bevel gear motor: 90° output to save space and optimize mechanical installation, with possible additional reduction.
For more details, check our options and accessories sections.
The maximum operating air pressure for a modec pneumatic motor should not exceed 6.2 bar . It is essential to ensure that the air supply matches the motor's specifications to operate efficiently and safely.
Additionally, the compressed air should have a dew point temperature below 10°C to prevent moisture issues.
